This was the main reason that sent me off making Object#duck to
map method names to the way you need:

http://rcrchive.net/rcr/show/318

My most common usage now is:

set.duck(:===,:include?)

It still puzzles me why some people wouldn't want something
like this in the ruby core.

I use this quite a bit with my grammar project.  Several of my
basic methods need an argument that responds to ===.
